I was wondering if you were actually removing it or if she was measuring it stretched on the seat...
Are you using the seatbelts? Not sure if they are same as my 75, but I am looking for the front center belts with good plastic shells the belt goes through. and my shoulder belt, especially driver is faded. Even tried dye and it only darkened a little.
I'll see if the Sport has belts. The belts from the Swinger look awesome, and they're black. I'll be using them if the others are gone. If not, I'll give you whichever set i aint using (obviously the second best set! But they'll be free!)
